So now Aqib Talib is a completely irreplaceable player on the New England Patriots? Good lord....very few players are irreplaceable on a Bill Belichick team. It's certainly possible that Belichick will appreciate what having a more physical CB brings to this defense in terms of options and aggressiveness, but that hardly means that Belichick will be sitting scared in a corner if Talib moves on, or that he'll somehow be forced into overpaying for him. It will all depend on the monetary demands, but all accounts point to him not accepting anything below market value, and with a lot of key free agents coming up over the next 18 months there will be some tough and unpopular decisions that will need to be made. There are certainly other talented man coverage CB's that play football in the NFL who may be explored if Belichick feels that they may save money and provide better value. The main goal will likely be to continue the scheme that is working, and believe it or not---other teams are also successful at it even though they don't have the services of the future HOF caliber Talib.
